Chris McQuarrie recently revealed that he approached Fox to write a bible for their superhero films including the X-Men and Fantastic Four which would have also featured "interlocking" films. He even met with Tom Rothman about it, but then never heard back. Mark Millar would eventually be hired as creative consultant. It would have been interesting to see what McQuarrie would have come up with, given the fact that his "The Wolverine" script has been so praised.
